Vintage Cast Iron Guide: Identification, Value, and Restoration

Vintage Cast Iron Guide helps you identify what you’re actually holding — a genuine Griswold or a well-faked one, an early Wagner or a later reissue, a discontinued Lodge pattern worth real money or a common pan worth using rather than selling. We cover identification, dating, value, restoration, and where to buy and sell with confidence.

Start Here

New to collecting cast iron? Start with the essentials.

A rusty skillet at a yard sale could be worth $20 or $2,000 — the difference is almost always in the maker, the marks, and the condition. Here’s how to start telling them apart.

Griswold Cast Iron

The name every collector wants to find.

Griswold is the most sought-after name in vintage cast iron, and also the most faked — knowing the real marks from the reproductions is the single most valuable skill a collector can have.

Wagner Cast Iron

Griswold’s biggest rival, and a collection all its own.

Wagner made some of the best cast iron cookware of its era, often at a lower price than Griswold today — which makes it one of the best entry points for a new collector.

Vintage Lodge Cast Iron

Still in production — but older pieces are their own market.

Restoration & Seasoning

Bring a neglected find back to life, the right way.

A rusty, sticky, or neglected piece can usually be restored — but the wrong method can strip value along with the grime. Here’s how to do it without ruining a genuine find.
